AudioQuest: K2 Speaker Cable
At the peak of AudioQuest's Flat Rock series sits K2. Just like the mountaintop, from this vantage point there are very few options to look up toward. K2 combines Solid Perfect-Surface Silver Conductors with DBS and AudioQuest's most successful Double Star-Quad Geometry. K2 will lift the sound of your system to near tropospheric heights.
SOLID PERFECT-SURFACE SILVER (PSS) CONDUCTORS
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
DOUBLE STAR-QUAD GEOMETRY
The relationship between conductors defines a cable?s most basic electrical values (capacitance and inductance). However, even when those variables are kept in reasonably neutral balance, the particular geometric relationship between conductors greatly affects the sound. ?Star-Quad? geometry is not only vastly superior to conductors run in parallel, but also to the same conductors as two twisted pairs.
MULTI-LAYER CARBON-BASED NOISE- AND CROSSTALK-DISSIPATION SYSTEM
This cable's negative conductors are covered with partially conductive Carbon-Loaded Polyethylene. This remarkable material reduces radio-frequency garbage being fed back into the amplifier. The sonic benefit is exactly the same reduction in "hash" and improved dimensionality that comes whenever RF interference is reduced in an audio circuit. In addition, a carbon layer damps interaction between positive and negative conductors, and an external Carbon-Based NDS System reduces external interference.
DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements.

FOAMED-POLYETHYLENE INSULATION (FOR ALL POSITIVE CONDUCTORS)
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Tower, however, uses air-filled Foamed-Polyethylene Insulation on both conductors. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
